' SELF LOCKING JIB sLDE Filed Nov. 2l, 1960 VINCENT KANSER 3,132,621 SELF LCIING .IIB SLIDE Vincent Kanser, 59 Forest Ave., Gien Ridge, NJ. Filed Nov. 21, 1960, Ser. No. '70,797 7 Claims. (Cl. 1i4108) The present invention relates to marine hardware and, more particularly, to an improved self `locking jib slide. Heretofore, the luif (or forward leach) of a jib was slidably attached to a stay wire or rope (extending from the bow eye to the upper portion of the mast) by conventional jib slides which were secured to the bolt rope or bolt wire reinforced edge of the jib and which were slidable in the stay wire or rope.

Recently the reinforcing bolt ropes (which rot) and the reinforcing bolt wires (which rust) for the jib have been eliminated. The edge portions of the jib are now reinforced with a .cloth tape, such as a nylon, Orlon or Daeron tape. AThis cloth tape covers both sides and is sewed to the edge portion of the jib.

Nylon is the generic or common name for a series of polyamide resins made by the polymerization of the hexamethylenediamine salt of adipic acid. Orion is a registered trademark owned by E. I. du Pont de Nemours & Co., Wilmington, Del. `and is a synthetic liber made principally from polyacrylonitrile. Daeron is a registered trademark owned by E. I. du Pont de Nemours & Co., Wilmington, Del. and is a synthetic fiber made by the condensation of dimethyl terephthaiate and ethylene glycol.

A general object of the present invention is the elimination of the difculties and defects of the conventional jib slides by the provision of an improved jib slide which is adapted for permanent attachment to a tape reinforced edge portion of the jib; which will not tear loose from such edge portion of the jib; and which can be quickly and economically attached to the edve portion of the jib.

Another object of the present invention is the provision of an improved jib slide which is self locking and will not become detached from the stay wire unless such improved jib slide is manually removed therefrom.

The aforesaid objects of the present invention and `other objects which will become apparent as the description proceeds are achieved by the provision of an improved jib slide having a iirst leg disposed on one `side of the edge portion and provided at one end with a first hook `extending beyond the edge portion, a second leg on the other side of the edge portion and provided at one end with a second hook in abutting engagement with the first hook. The second leg crosses over the iirst leg to lock the hooks together. The legs are provided at their other ends with means for securing the legs to the edge portion.

With specific reference to the form of the present invention illustrated in the drawing, and referring particularly to FIGS. l and 2, an improved jib slide of the present invention is designated by the reference numeral 90, which jib slide is shown positioned on a tape reinforced edge portion 92 of a jib preparatory for attachment thereto. This jib slide 90 is formed from a single piece of rigid but resilient metal wire or rod, suitably stainless steel.

A iirst'liook leg 94)c (FIGS. 1, 2 and 2A) carrying a first hook 96f on its outer end is disposed on the front side of the edge portion 92 and extends diagonally inward, terminating in the left-hand side (FIG. l) of a trst eyelet 98j. The first hook 96f extends beyond an edge 99 of the edge portion 92. A first U-leg i of a U-shaped central support member extends from the right side (FIG. l) of the` iirst eyelet 901 and terminates in the right hand side of an arcuate portion 102 of the U-shaped central support member, which arcuate portion 102 crosses over and supports the edge 99 of the edge portion 92. Such edge portion 92 is seated in the arcuate portion 102. A second U-leg 100s extends (on the rear side ofthe edge portion92, FIG. 1) from the left-hand side of the arcuate portion 102 and terminates in the left-hand side (FIG. 1) of a second eyelet 98s. As shown in FIG. ,1, a second hook leg 94s extends diagonally from the right hand side of the second eyelet 98S to the edge 99; crosses over the first hook leg 94]c but on the opposite side of edge portion 92; and carries a second hook 96s, which second hook 96s is disposed in abutting engagement with the iirst hook 967 and is oppositely directed with respect to said iirst hook 961. Because the hook legs 94j and 94s cross over each other (as viewed in FIG. l), they may be said to be in criss-cross relation. p

In order to secure the jib slide 90 to the edge portion 92, conventional fastening means, such as a screw or bolt means, suggested at 91, is inserted through the first eyelet 9Sf, the edge `portion 92 and the second eyelet 98s, with attendant aligning of and locking together of the eyelets 98f and 98s `as a fixed spring pivot.

` It will be noted from a consideration of FIG. 1 that the first hook leg 941 and the second hook leg 96s cross over each other (inthis case on opposite sides of the edge portion so that the hooks 96f and 96s carried thereby are spring-biased or locked together). As a result, once a stay wire (not shown) is disposed within the hooks 96,1c and 96s, such stay wire (not shown) cannot become unattached from the hooks 96]c and 96s unlessmanually removed therefrom. 1 p

To facilitate insertion of the stay wire (not shown) into the hooks 96j and 96s, the lower inner side wall of each hook 96f and 96s is provided with a guide level, which guide bevels comprise a guide aperture 104.

Alternatively, to simplify the jib slide 90, the U-shaped central support member comprising the iU-legs 100f and 100s and arcuate portion 102 may be dispensed with.

In order to provide `alternative guide means for the introduction of the stay wire (not shown) between spring locked hooks 96)" and 96s', lower ends 106]" and 106s (FIGL 3) of the hooks 96]" and 96s', are bent outwardly to provide an enlarged V-shaped guide aperture 10411.

Alternatively, as shown in FIG. 4, the terminal portions 108f and 108s of the hooks 96f and 96s" may be extended and bent inwardly toward the associated adjacent hook. The ends of the terminal portions 1081" and 108s are provided with a circular end slot (of the same diameter as the wire or rod of which the jib slide 9i) is fabricated) so that such terminal portions 1081" and 198s will receive the associated adjacent hook. This arrangement shown in FIG. 4 provides a suitable guide aperture 1Mb. To assemble the hooks 96s and 96f" to a cable, these hooks are spread apart against resiliency of legs 94s and 941, thereby permitting terminal portions 10320 and 168s to separate from their seated relation so that the cable may be passed into and be received by the hooks.

In order to provide still further locking means for hooks 96f'" and 96s, the free end of each hook may be extended, as shown in FIG. 5, and bent in the generally sinusoidal shape (shown in such FIG. 5) to form locking tabs 1`rf and lfis", which tabs Iiif" and 198s are biased against the respective hook legs 9470" and 94s".

Alternative Embodl'ments of the Jz'b Slide In FIG. 6, a jib slide 96C has a first eyelet 98f disposed on the front side of the edge portion 92. A first hook leg 94] extends from the left hand side of the eyelet 98j diagonally to the edge 99 of the edge portion 92 with the first hook 96f disposed in its usual position. A second hook leg 94s extends from the right side of the first eyelet 98f; is inserted through an aperture 101 in the edge portion 92; and extends diagonally (on the back side of the edge portion 92 to the edge 99 where the second hook 96s is in abutting and spring locking relationship with the first hook 961). As described for FIGS. l and 2, the legs 94f and 94s cross each other (are crisscrossed) so that spring-locking of the hooks 96f-9s is facilitated. Conventional fastening means (such as a bolt or screw, not shown) is inserted through the eyelet 98]c and the edge portion 92 to secure the jib slide 90C to the edge portion 92. An advantage of this construction is that the hooks 961 and 96s are disposed closer to the edge 99 of the edge portion 92, since the U-shaped central support member (of FIGS. l and 2) is not employed.

As shown in FIG. 7 (and in a jib slide 90d shown therein), the hook legs 94j and 94s are crossed on the same side of the edge portion 92 (in this case the front side). In order that the hook legs 947" and 94s" will be disposed in substantially the same plane, one of the hook legs, for example the second hook leg 94s", is provided with a saddle or generally U-shaped central portion 110 for receiving the hook leg 94f and for pro- Viding a spring pivot at 112. The upper portions of the hook legs 941i and 94s are bent over an aperture in the jib (or a grommet 114) and leg extensions 113f and 113s thereof extend diagonally to, and beyond, the edge 99 (on the other side) of the edge portion 92. An extending U-shaped terminal portion 116 (of the single wire or rod from which the jib slide 90d is formed) is then bent back over the edge 99 and against the edge portion 92 (backed up by the leg extensions 113f and 113s). Use of the hook structure shown in FIG. 4 is effective to increase the spring locking force on the hooks 96]c and 96s.

Alternatively, as shown in FIG. 8, the leg extensions 113/" and 113s may terminate in an eyelet 115, which eyelet 115 is disposed short of the edge 99 to permit use of either conventional fastening means (such as a bolt or screw, not shown) through the edge portion 92 and eyelet 115 or use of sewing with cord to attach the jib slide 90d to the edge portion.

As shown in FIGS. 9 and l0, a jib slide 90e, similar to jib slide 90d (FIGS. 7 and 8), may be made from metal strip. A hook leg 94e carrying a hook 96e is disposed on one side (i.e. the back side, FIGS. 9 and l0) of the edge portion 92, and terminates (at the opposite end to the hook 96e) in an arcuate portion 117 which straddles either an aperture in the edge portion 92 or the grommet 114. A leg extension 113e extends diagonally from the arcuate portion 117 down the other (or front) side of the edge portion 92 and beyond its edge 99. A terminal portion 116e of the ieg extension 113e is bent over the edge portion 92 to lock the jib slide 9de in place.

To provide locking means for the hook 96e, its free end is provided with a locking tab lfiSe, similar to the locking tabs 153 shown in FIG. 5.

It will be appreciated that alternatively the leg extension 113e can be terminated short of the edge 99 and such leg extension 113e provided with an aperture 118 (FIG. 9). Such leg extension 113e is then secured to the edge portion 92 by either sewing the aperture 118 to such edge portion 92 or by inserting conventional fastening means (such as a bolt or screw, not shown) through the aperture 11S and the edge portion 92.

It will be recognized by those skilled in the art that the objects of the present invention have been achieved by the provision of an improved jib slide which can be quickly, permanently and economically aiiixed to a tape reinforced edge portion of a jib. Such improved jib slide will not tear loose from the jib and permanently locks the associated stay wire to the jib slide.

While in accordance with the patent statutes aV preferred embodiment of the present invention has been illustrated and described in detail, it is to be particularly understood that the invention is not limited thereby.
